The NSD Powerball is a finely engineered and precision crafted gyroscope consisting of a rapidly spinning rotor enclosed in a solid hand held sphere. The inner rotor (gyroscope) is set in motion using the starter cord provided. Spinning at (approx) 2,500 RPM the user will feel the gyroscopic forces kick in. It is now up to the user to increase the speed of the rotor by making rotational movements with their wrist, keeping in synch with the spinning speed of the ball. The faster you rotate the Powerball the greater and more extreme the forces become.
The amazing 350 Hz Pro Metal Powerball, including RPM Counter is simply outstanding. It generates pulverising torque even at low speeds. It is supplied with a beautiful perspex magnetic case.
